To all whom it may concern Be it known that 1, JOHN \VALDHEIM, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented C8Ii32t1Il IlW and useful Improvements in Typewrlting Machines, of whichthe following isa specification. I

This invention relates to fan-folded typewriting machines of the continuous billing type, in which a composite web is fed around a cylindrical platen, the composite web comprising several plies of work-sheets having successive corresponding forms printed thereon, said plies being sometimesseparated from each other their side edges to form a fan-folded web, the various plies having carbon-sheets interleaved therebetween which are shiftable lengthwise of the pliesfrom form to form. The invention relates means for facilitating relative displacement or shifting of the carbon-sheets and the .of forms.

work-sheets.

The Underwood continuous billing typewriting machine which is adapted fol-this kind of work employs a cylindrlcal platen, and in said machine the platen is displaced upwardly from its usual printing POSltlOn by means of a swing frame,preliminary to shifting ofthe carbonsheets, so that tnat portion of the composite web includingthe carbon-sheets may be straightened out in order that the carbonsheets may be readily shifted along the work-sheets to a I There is also employed in said machine a table extending rearwardlyfrom the platen upon which a carbon-carrier '15 mounted to travel back and forth over said from the platen, said carbon-carrier having the. ends of the interleaved carbon-sheets connected thereto, and said carbon-carrier being movable rearwardly by a handle while the work-sheets are drawn upwardly to a suitable gage, after which the platen is again lowered to its typing position,'in which position the typed An object of "the present invention is to facilitate the relative shifting of the carbon-sheets and the. work-sheets without lifting the platen, the platen remaining, in the present invention, always its usual typing position. To this end, there 1s provided a table extending rearwardly from the platen,

and sometimes joined at more particularly to fresh set The platen may pivoted portion of the said tablchavin'g' a carbon-carrier movable thereon towards and awayfromthe platen. The carbon-carrier in the present invention, however, is used to move rea-rwardly, or, in other words, to withdraw the composite web around the platen to free the leading ends of the carbon-sheets fromthe platen; To this end, said table comprises two sections, a relatively fixed section secured to the typewriter carriage and traveling therewitln'and a pivoted section which may be swung about its pivot toraise pivoted section of said table toa plane substantially parallel with the usual rear papertable of the typewriting machine, sothat that portion of the composite web including the carbon-sheets occupies a straightened out position. Inswinging up the pivoted portion of said table, the carbon-carrier is also caused to travel upwardly and rearwardly over said table section, this being brought about by means which may comprise a cord or hand, one end of which may be secured to the relatively fixed portion of said table, said cord being conducted over a wardly on said-swingingtablc portion, thus I worksheet-s to be drawn rear- 'wardly with the ca-rbon sheets, the usual ausing the feed-rolls being released withdrawing operation.

"After the carbon-sheets have been freed from the platen, the pivoted portion of said table is retained in its inclined position. The feed-rolls may then be thrown on to during this webits rear end to bring said w grasp the leading edges of firework-sheets.

then be rotated to advance the work-sheets relatively to the carbon sheets, the extent of forward feed of the work-sheets being determined by a suitable gage at the delivery side of the platen. The table'may then be lowered, and the composite web may be advanced to bring the leading edges of the work-sheets to a second gage, during which time the leading edges of the carbons are also brought to the printing point, and the bottoms of the typed forms are brought to a suitable knife, by which said typed forms may be severed.

A light spring is provided to take up the slack produced in the carbon-carrier-controlling cord when the pivoted section of thetable is swung down from its inclined position. Said cord is provided with an enlargement to serve as a stop to abut against a portion of the relatively fixed section of said table to render said cord effective to draw the carbon-carrier over the pivoted section of said table. The upward and rear ward travel of the carbon-carrier is limited by a fixed stop on the pivoted portion of said table. Consequently the cord in its stretched condition, when the carbon-carrier is against said stop, limits the swinging movement of the pivoted portion of said table, or, in other words, establishes its ininclined position With reference to the platen.

Both sections of said table are supported at their rear ends by suitable rollers secured thereto, said rollers bearing on a rod secured to a frame extending rearwardly from the main frame of the typewriting machine.

Other features and advantages will hereinafter appear. v I

Figure 6 is a partial sectional side view similar to Figure 5, and shows both the work-sheets and carbon-sheets advanced, after gaging as in Figure 5, to a position where the completed leading work-sheet sections may be severed from the pack, as shown in dot-and-dash lines in this figure.

Mounted on a rail 7 in a typewriter-frame 8 is a movable carriage 9 in which is supported aplaten 10, which has feed-rolls 11 and 12 co-operating therewith in the usual manner to feed work-sheets through the machine. Fastened to the rear of the carriage 9 is a rear paper-table 13, and fastened to the top of the carriage 9 and in front of the platen 10 by means of brackets 14 is a front paper-table 15, which carries a gage-bar 16 furnished with gages 17. and 18 and also a web-severing knife'19 which may be adjusted to various positions. F astened to the rear of the frame 8 is a sub base 20, which maybe furnished with a rear rail 21. Supported in the rear on the rail 21 by means of rollers 22 fastened in brackets 23, and in the front by means of brackets 24 which are fastened to the rear of the carriage, is a sub-frame 25. Depending from the rear of the sub-frame 25 is a bracket 26 which supports a spring-barrel 2?, the

purpose of which will be disclosed hereinafter.

Near the front of the sub-frame 25 are two upstanding cars 28, to which is movably fastened, by means of pivots 29, a work-presenting frame 30 which may have side members 31, a front crossaneinber 32 and a rear crossmember 34. Mounted on the side nembers 31 by means of brackets 35 are rollers 36, which support the worlepresenting frame 30 upon the rail 21 when the former is in its normal position. liifounted on the rear crossmember 34 between brackets37 is a sheavewheel 38. The tops of the side members 31 may be furnished with rails 39, which may be extended beyond the-rear cross-member 34, as at 40, to support a paper-guard 41. Paperuides 42 and 43 may be mounted on the front crossmember 32 and on the paperguard 41 respectively. A carbon-carrier 44,

furnished with a plurality of carbon-holding blades 45, may be mounted by means of rollers 46 to move forwardly and baekwardly upon the rails 39. A stop 47 may be placed at the rear of the work-presenting frame 30 to limit the backward movement of the carbon-carrier 44. A handle 48 may be mounted to the rear of the pivot 29 on the workpresenting frame 30 for the purpose of rais ing and lowering it. 49, fastened by one end, as at 50, to the spring-barrel 27 and furnished with a stop 51, may be led through an opening 52 in the rear of the sub-frame 25, thence over the sheave 38 and fastened to the rear of the carbon-carrier 44, as at 53.

In operation, the work-presenting frame 30 is first allowed to remain horizontal, as in Figure 1, with the carbon-carrier 44 drawn to the extreme rear by means of the springbarrel 27 and cord 49. The leading edge of a continuous pack 54, made up of a plurality of superimposed work-sheets 54 is taken from a suitable container 55, threaded through a pair of restraining rollers 56,

which may be fastened to a suitable supporting table, led over the paper-guard 41, between the carbon-holding.blades 45, and is drawn through carbon-sheets 57 until the leading ends of the latter are in proper po- A suitable cord or belt 0 sition in back of the leading ends of the worksheets 54 to transferthe first line of matter that is to be typed upon the first work-sheet section. v

The leading edge of the pack so formed, with the carbon-sheets 57' interleaved between the work-sheets 54 is now brought forwardand fed underneath the platen 10 through the co-operation of the feed-rolls lland 12 until the first line of writing on the first work-sheet section is brought to the printing-point. All of the matter that is to appear on a single work-sheet section is now typed upon the first of those sections, and during this typing operation, as the pack 54 is advanced by line-spacing, the leading edge thereof is led underneath the'severing knife 19. The conclusion of the'typing op eration that completes the first work-sheet section will find the ack 54 in a position similar to that shown in Figure 1. The carbon-carrier'44 will have been advanced forwardlyupon the work-presenting frame 30, due tothe pull of the carbon-sheets' 57 against the tension of the spring-drum '27. The operator now grasps the handle 48 in her left hand, draws it forwardly and downwardly, and by so doing swings the workpresentingframe 80 upwardly and forwardly around the pivot 29. When this operation is begun with the left hand, the feed-rolls 11 and 12 are thrown OiIWitll the right. In raising the work-presenting frame 30,-'the cord 49 is drawn from around the springdrum 27, and through the opening 52 until' the stop 51 prohibits any further unwinding. The work-sheets 54*,together with the carbons 57, having been released from the gripping-pressure of the feed-rolls 11 and 12 upon the platen 10, and' the cord 49having been stopped from further unwinding, the cord 49 now draws the carbon-carrier 44 toward the rear of the work-presenting frame 30 and carries the carbon-sheets 57 along with it until any further raising of the work-presenting frame 30 is stopped by having the rear of the carbon-carrier 44 come in contact with the stop 47. Simultaneously with the withdrawal of the carbonsheets 57, the leading ends of the worksheets 54 are also withdrawn from'around the platen 10 by the raising of the workpresenting frame 30, their trailing ends be ing held stationary during the raising oper ation by the clamping action of the rolls 56;

Both withdrawals occurring at the same time, the carbon and work sheets retain their respective positions relative to one another. hen the work-presenting frame. 30 has been raised to the limit, the carbon-sheets 57 will be entirely free of the feed-rolls 11 and 12, but the leading ends of the worksheets 54 will still remain in a position where they'will be engaged by the feed-roll 12 when it is again thrown on. The various parts of the mechanism will now have reached positions similar to those shown in Figure .4. Retaining the work-presenting frame 30 in its raised position'with her left hand, the operator throws on the feed-rolls 11 and 12 with her right hand, and then, still with her right hand, rotates the platen 10 by turningv the platen-knob until the lead ing ends of the work-sheets 54 have reached the long leg of the gage 17. While this lastdescribed operation is being performed, the carbon-sheets 57- are restrained from advancing'withthework-sheets 54 by means of the cord 49 attached to the carbon-carrier 44. This operation withdraws the carbons 57 from the first work-sheet section entirely, and brings their leading edges to a vposition for transferring the first line of writing on the second work-sheet section.

The work-presenting frame 30 is now lowered to its normal position, which creates a slack in the trailing edge of the pack 54, as shown'in Figure l, and also allows the drum 27 to takeup the cord 49; The operator again rotates the platen 10 with her right hand, drawing the pack 54 forward together with the carbon-carrier 44 against the tension of the spring-drum 27 'u ntil the leading ends of the work-sheets 54 touch the long leg'of the gage 18."; This brings the severing point between the first and second work-sheet sections opposite the cutting edge of the knife 19, and also brings the first line of writing on the-second work-sheet section to the printing point, as shown in Figure 6. The completed first work-sheetsection' may now be severed fromthe pack 54, and the operation repeated.

Variations may be resorted to within the scope of the invention, and portions ofth'e improvements may be used without others. Having thus described my invention, I claim: l
